Disaster recovery is an organization’s method of regaining access and functionality to its IT infrastructure after a natural or human disaster, like equipment failure or cyberattack.
To prepare for potential disaster situations, organizations can prepare a disaster recovery plan, which includes a recovery point objective (RPO) and recovery time objective (RTO). RPO states the frequency of data backups that the organization requires. RTO determines the maximum amount of downtime that the organization can handle. These metrics create limits to guide the choice of IT strategy, processes and procedures that make up an organization’s disaster recovery plan.
Disaster recovery is one aspect of business continuity.
